Abstract
The switch has at least one moving contact part bridging stationary contacts and containing two switching positions, i.e. ON and OFF. The moving contact part is prestress in one position direction and held in the other one by a permanent magnet. The permanent magnet field can be affected by the magnetic field of an electromagnet such that the prestressed moving contact part can be moved to its other switching position when the electromagnet field has been built-up. Preferably the electromagnet is excited by a control pulse from a control electronic.
Description
The present invention relates to a kind of appliance switch, particularly a kind of tumbler switch, it has a switch case, the switch annex of one executive component is inserted in this switch case, at least one moving contact and some fixed contacts overlap joint, this moving contact has two position of the switch: an on-position and an off-position, this moving contact on a direction of the position of the switch by biasing, on the other direction of the position of the switch, hold, but executive component deflection is to move moving contact by the switch annex by a magnet.
This switch influences the position of the switch with magnetic.Its shortcoming is, must pass to constant current in the magnet, and this causes higher energy consumption on the one hand, on the other hand, and easy breaking out of fire when magnet damages.In addition, this magnet also is quite expensive.
Therefore, task of the present invention is to design the alleged the sort of appliance switch of this specification beginning like this, makes the position of the switch keep connecting reliably, in addition, but do not need just maintained switch position of consumed power, and therefore avoid fire, at last, should make the cost of switch own low.According to the present invention, this task is done in such a way that described magnet is made of permanent magnet, and its magnetic field can be influenced like this by the magnetic field of an electromagnet, and when forming the magnetic field of electromagnet, the moving contact that keeps by biasing can be switched to its another position of the switch.By the selection of electromagnet, need not current drain and just can simply and reliably keep a position of the switch.Only when needs unclamp this position of the switch, just connect electromagnet,, make the biased position of the switch to readjust to come the magnetic field of superposition permanent magnet like this.Adopt the present invention also needn't worry the electromagnet overload again, because just as mentioned above, electromagnet just uses momently, other the time then keep the original position of the switch by permanent magnet.Prerequisite of the present invention is to prepare less electromagnet, because as long as electromagnet is big to overcoming and the relevant magnetic field, another position of the switch that imposes bias voltage.
When electromagnet need produce magnetic field, to its in short-term in addition current impulse be favourable.Of short duration apply electric current and can further simplify electromagnet by this, because now no longer need regulating magnet just can offset the magnetic field of permanent magnet.It is favourable that this current impulse produces by a kind of known electronic-controlled installation, can have a kind of simple and cost is reasonably constructed like this.
In a specific embodiment of the present invention, under switch is in on-state, just can make switch transition to off-position by pulse making alive on electromagnet that electronic-controlled installation produced, thereby controlled electrical equipment (for example coffee machine) is separated with electrical network again itself.When appliance switch itself owing to unexpected its on-position that is transformed into, and the plug of electrical equipment be directed to electrical network finish this switch advantageous particularly under the situation of connection.Because when voltage is connected, produce a current impulse at once, so appliance switch itself comes back to its off-position, and household electrical appliance (for example coffee machine) and electrical network disconnection that this appliance switch is housed.
Further advantageously, after reaching a preset time, on electromagnet, produce one by the time element in the electronic-controlled installation and cut off pulse.The electrical equipment that this break impulse has guaranteed to be equipped with this appliance switch is closable, and can by mistake not connect for a long time with electrical network.Certainly, break impulse can be produced by electronic installation by another kind of inevitable phenomenon.
Recommendablely be, to be used to keep on-position setting, the permanent magnet that cooperates with a metal counterpart and/or this counterpart to float supports, because can guarantee permanent magnet and metal counterpart best alignment to each other like this, and just can need the Z-TEK of the maximum of permanent magnet not big by the two is alignd, thereby can simplified construction, in addition, also the power designs of electromagnet must be able to be hanged down by such support, because do not need to overcome high-intensity magnetic field.In a specific embodiment of the present invention, the switch annex of predesignating the conversion of upset moving contact is positioned at a side of the gyroaxis of moving contact, and a return spring is arranged on the opposite side of gyroaxis.Guaranteed a kind of simple structure of switching device by this measure.In addition, by installing and making, return spring and switch annex are easy to insert.Advantageously, in the location of a cut, switch annex part is stretched in the moving contact, thereby obtain a kind of guidance mode of moving contact, also enlarged the function of switch annex on the other hand, because if the switch annex is made by a kind of optical material, be easy to its free end is arranged on the light-emitting device, so just can remind the state of user's switch.
Further advantageously, when switch case was provided with an opening for executive component is passed, the collar on the executive component was overlapped on the edge of opening, and this edge preferably is inserted in the groove of executive component.Between shell rim and executive component, produce a kind of labyrinth sealing by this groove.Guaranteed that by sealing dirt can not reach the inside of switch case.Have the recessed such setting of flute profile of collar, make collar be overlapped on the whole switch case.
Advantageously, electromagnet is arranged in the switch case, and its coil is around permanent magnet, to guarantee to make in case of necessity the magnetic field of permanent magnet and the magnetic field superposition of electromagnet, thereby improve the effect of permanent magnet, and make moving contact pass through return spring (33) disengagement fixed contact.

Illustrated appliance switch constitutes a tumbler switch 10.It is placed on it that it has box switch case 11, one executive components 12, and executive component is made of hood-shaped parts 13 and bottom parts 14.
The wall or the fit walls of 16 expressions, one household electrical appliance, for example an automobile among the figure.Tumbler switch 10 is arranged on the wall 16, or rather, support arm 15 is supporting the back side of wall, and in wall perforate 17, have the projection that is not shown specifically among the figure, this projection is arranged on one between hood-shaped parts 13 and the lower member 14 and empties in the part, and executive component can be done gyration around described projection.
Executive component has a switch annex 18, and the switch annex has side rib 19.The through hole that switch annex 18 passes on the moving contact 20 contacts with moving contact, and utilizes rib to be supported on this moving contact.
When doing gyration, executive component 12 drives moving contact 20 motions.Moving contact 20 and fixed contact 21 overlap joints, at this, a spring 33 remains on off-position with tumbler switch.One end of spring is arranged on the fixed contact 21, has a knife-edge support 22 on the fixed contact, and supports the single-revolution axle of moving contact 20 thus.
Moving contact also is second strong point of spring 33 simultaneously, and or rather, spring is between gyroaxis 22 and the moving contact 20, and keeps off-position thus.Spring is further strained when executive component 12 makes switch transition, and moving contact 20 is transformed into the position of representing with fine rule, and meets another fixed contact 21, and two contacts 21 are connected.
Be provided with a lighting device 23 below switch annex 18 free-ended, the switch annex itself is to be made by light transmissive material, therefore, is illuminated at the hood-shaped parts 13 of on-position.
The executive component 12 still supports of a metal counterpart 26 own, this metal counterpart is floated and is arranged on the opposite of a permanent magnet 24, and pass floating support device and just in time drop on the permanent magnet, two planes of counterpart and permanent magnet can keep static each other in the conversion moving process of executive component.
One electromagnet 25 is round permanent magnet 24.
As mentioned above, permanent magnet 24 cooperates with metal counterpart 26 on being arranged on executive component 12.
Feed a current impulse on the magnet spool now, make coil 27 produce a magnetic field, the magnetic field of this magnetic field cancellation permanent magnet 24.Spring 33 makes moving contact 20 leave a fixed contact 21, thereby cuts off electric current, and switch and executive component jump back to position shown in Figure 1.
When operating operation element 12, in other words, during along clockwise revolution, metal counterpart 26 contacts with permanent magnet 24 again, thereby reaches on-position.Realized the ON Action of moment by magnetic force.
The lower member 14 of executive component 12 has a collar 30, is clearly shown that in Fig. 1, and collar surrounds the edge 29 of perforate 28 fully.The wall that another and collar separate also is set simultaneously, constitutes a receiving slit 31 therefrom, this groove labyrinth type ground is around the edge 29 of perforate.
Clearly visible from Fig. 2, all stretch out switch case from the vertical view collar in each side except support arm.
Schematically illustrated electronic-controlled installation 32 among Fig. 3.Electronic-controlled installation 32 has two tasks, a task is to produce a pulse when adding a voltage on switch, another task is through behind one section preset time, or provides another pulse under other condition, and this pulse becomes its initial position with switch transition.In other words, electromagnet influences the magnetic field of permanent magnet 24, it is produced cut off action.Electronic-controlled installation has a kind of known structure.Can constitute dexterously with a kind of simple form of implementation, perhaps constitute by an IC or a processor.Importantly, produce two pulses that can obtain an actual off-position at least.
Making operation element when if electrical equipment moves, the user do not know yet, and electrical equipment passes to line voltage, and then appliance switch itself can the whole electric current that has, and another device that is equipped with this appliance switch also can have electric current.
Yet, owing to when having voltage on the electronic-controlled installation 32, produce a pulse,, cut off action thereby switch 10 is transformed into automatically so on the coil 27 of electromagnet 25, produce a magnetic field, in other words, appliance switch cuts off another device that this switch is housed automatically.
Further illustrate below.Make pulse of same generation when executive component 12 is made ON Action, this pulse produces an electromagnetic field by electromagnet, and this electromagnetic field is offset the magnetic field of permanent magnet.Yet, because moving contact reaches its on-position when the switch annex is made ON Action, and the duration of one section pulse of executive component maintenance, so although pulse is arranged, appliance switch still keeps its on-position.Only behind the unclamp operation element, could pass through a pulse of changing, for example reach off-position by a delay unit.
At Fig. 4 similar switching device of one and first embodiment shown in the embodiment shown in Figure 6.Illustrated still tumbler switch 10, it has a switch case 11, and its open side is sealed by an executive component 12, also has hood-shaped parts 13 on executive component 12.
The lower member 14 of executive component is designed to collar shape.It is buckled on the opening of case shape switch case.Executive component 12 is arranged on the switch case rotationally.For this reason, on both sides relative on the diameter of switch case, have pivot pin 34, the supported hole engagement on these two pivot pins and the executive component 12.
For switching device being remained on the wall 16, wall is provided with an opening 17.Be provided with sickle-shaped protrudingly 36 in the two opposite sides of opening 17, the sickleshaped of the analogous shape on it and the executive component is emptied part 37 engagements.Like this, switch is fixed in wall 16 by executive component and hood-shaped parts 13.Make the switch alignment by support arm 15 is set on switch case, support arm 15 is caught the back side of wall.
Different with first embodiment is that switch annex 18 has a perforation 38, and a compression spring 39 is set in it, and a sliding part 40 is housed on the free end of spring.This beans shape sliding part is changed this moving contact by sliding on moving contact 20.Moving contact turns round on blade 22, and to the conversion of the lap position shown in Fig. 5, two adjacent fixed contacts 21 overlap on lap position shown in Figure 5 from open position shown in Figure 4.And then also observe, lighting device 23 be located at always executive component 12 below, to obtain good illumination.
The spring 33 that moving contact is remained on an optimum position is provided with specifically like this, makes executive component by this spring pressurization, thereby makes moving contact 20 reach its open position shown in Figure 5.To point out also that at last electronic-controlled installation 32 is contained on the circuit board 41, as being clearly shown that among Fig. 6 basically.
As shown in Figure 4, switching device is positioned at its open position.In this position, spring 33 1 ends are contained in one in the housing 11 and empty in the part, and the other end withstands on the executive component 12.Moving contact 20 is turned back to the position of leaving a fixed contact 21.Our move in the direction of the clock now executive component or hood-shaped parts 13, then metal counterpart 26 is fallen on the permanent magnet 24.And then moving contact 20 is rotated counterclockwise on the fixed contact 21.Switch is in its on-position.By being positioned at the turn-on time of the electronic-controlled installation 32 qualification switching devices on the circuit board 41.One arrives the terminal point of this official hour, just produces a current impulse in the coil 27 of electromagnet 25.This current impulse produces a magnetic field, the magnetic field of this magnetic field cancellation permanent magnet 24 by electromagnet 25.Spring 33 pushes up position shown in Figure 4 with executive component, and simultaneously, moving contact 20 forwards its off-position to.To point out also that here each magnet spool always produces a current impulse when connecting electrical network.By this current impulse, each switching device all is transformed into its off-position.Also to further specify, also define the time that coil is connected electrical network, only produce a pulse, and on all the other times that switching device is connected, not provide electric current to magnet spool with assurance by electronic-controlled installation.If switch moves to its conduction position, position promptly shown in Figure 5 and do not connect electrical network, then this position of the switch is keeping always, produces a current impulse up to connecting electrical network, and switching device just is transformed into its off-position in moment.
To illustrate also that at last the circuit board 41 that electronic-controlled installation is housed is parallel to the longitudinal edge of switching device, as shown in Figure 6.Realize each current lead-through by this circuit board.
As noted above, the diagram form of implementation is just described the present invention by way of example, be not construed as limiting the invention, on the contrary, can also make various modifications and application to the present invention, for example, can replace the metal counterpart with another permanent magnet, this permanent magnet cooperates with first magnet, also can make this permanent magnet or metal counterpart not be set directly on the executive component, and be arranged on the moving contact, thereby make moving contact directly remain on its on-position, rather than pass through executive component.By the spring that contacts with moving contact, guaranteed that the moving contact stagnation pressure is on the switch annex of executive component.Switch shown in the figure also can constitute tumbler switch or push-button switch.This appliance switch for example can be used for household electrical appliance, as cooking machine, coffee machine or the like, perhaps is used for auto industry, for example connects or close a thin slice heater with it.
